Researchers have used machine learning and supercomputer simulations to investigate how tiny gold nanoparticles bind to blood proteins. The studies discovered that favorable nanoparticle-protein ...

Some key applications of gold nanoparticles include photonics, medicine and catalysis. 3 Gold nanoparticles have a high absorption cross-section in the visible and infrared regions, which can be tuned ...

The basic working principle of colorimetric sensing is colorimetry, which is a visible change in color that results from a chemical interaction between the sensing/detecting material and the target ...

Gold nanoparticles (AuNPs) are nanoscale particles of gold, typically ranging in size from 1 to 100 nanometers (nm). These nanoparticles exhibit unique physical, chemical, and optical properties that ...

Gold is a precious metal that has always fascinated humans. From Priam's Treasure to the legend of El Dorado, gold --regarded as the noblest of metals-- has been a symbol of splendour and wealth in ...

Health care professionals use tiny particles of gold (nanoparticles) for a variety of medical applications—from diagnostic imaging to cancer treatment. Gold works well for these applications because ...

A new method uses gold to assemble multi-element nanoparticles under mild conditions, offering improvements in catalytic activity and long-term stability. (Nanowerk Spotlight) The drive to engineer ...

Mesmerizing videos offer a new look at the ways crystals form. The real-time clips, described March 30 in Nature Nanotechnology, show closeup views of microscopic gold particles tumbling, sliding and ...
